GEARING.

Specification of Letters Patent.

Application filed August 31, 1914. SerialNo. 859,460.

To all whom it may concern:

Be it .known that I, HUNDLEY WIGGINS, a citizen of the United States, residing at San Angelo, in the county of Tom Green and State ,of Texas, have invented a new and useful Gearing, of which the following is a specification. I

The present invention relates to improve.- ments in gearing, and more especially adapted for use in connection with wind mills and other devices, whereby a rotary movement is adapted to be converted into a reciprocatory movement or vice versa, one object of the invention, being the provision of a novel form of mounting and connection for receiving the rotary operative means and-,from -which it transmits the desired reciprocatory motion. r

A- further object of the present invention, isthe provision of a simple, inexpensive and durable structure of this character, which is readily applied in use where it is desirable to convert a rotaryqm'ovement into a reciprocatory movement or vice versa.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and-arrangement of pa-rtsand in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawings-Figure 1 is a transverse sectional view through the main gearing showing the parts in the position they normally assume. Fig. 2 is a section taken on line 22 of Fig. 1. Fig. 3 is a view similar to Fig. 2 of a modified form. Fig. 4 is a section taken on the line l1 thereof. Fig. 5 is a view similar to Fig. 1 of still another modified form. Fig. 6 is a section taken on the line 6-6 of Fig. 5. 1

Referring to the drawings, and more particularly to Figs. 1 and 2 thereof, the numeral 1 designates the supporting standard which is tubular and provided with the forked end carrying the two terminals 2 and 3 the terminal 2 being provided with the re atively long journaling sleeve 4 while the terminal 3 is provided with the short apertured portion 5, and the operating rotatory shaft 6 is mounted in the sleeve 1, while disposed in the portion 5 is apin 7.

Mounted for reciprocation within the tubular member 1 is thepitman 8, which is PIOVlClBdwith the yoked end 9 connected by Patented Apr. 11, 1916.

a pivotal pin 10 to'the arm-11 of the intermediate operating member 12. This inter mediate operating member 12-,is provided with an internally toothed rim 13, and with the opposltely extending concentric studs 14 and 15. The stud 14 is mounted for rotation 1n one end of the arm 16 whose other end is loose on the shaft 6, while the stud 15 is rotatably mounted in one endofthe arm 11 which is loose on the pin 7. a

Fixed uponthe endof the shaft 6 and the arm 16 and disposed to'mesh with the internal gear 13 is a gear 18. It will thus be seen that as the shaft 6 is rotated, the gear 18 will itself be rotated and through the internal gear-l3 will impart movement thereto so as to cause the center of the member 12 13 carried by the member 12. This memberv 12 is revolubly mounted about a central transverse axis, there being a stud 15' projecting outwardly from the center of member 12 and revolubly mounted within an arm 17. This arm 17 is pivotally connected to the support 3 at a point in alinement with the shaft 6. In order to support the internal gear 13 in mesh with the gear 18, thus to take the place of the arm 16 shown in F igs- 1 and 2, an idler gear 20 is journaled on a central stud 19 revoluble with the member 12', this idler gear engaging the gear 18 and being adapted to travel therearound during the actuation of the gear 13 1 by gear 18.

and carries upon its respective ends, the two wheels or rollers 21 and 22, the peripheries of which bear as illustrated in Fig. 5 upon the shaft 6* and pin 7 and thus constitute the desirable spacing means for the member 12 during the rotation of the same with its shaft 23 moving in a circle with the shaft 6 as its axis, thus imparting the desired reciprocatory movement to the pitman 8*.

It will thus be seen that in all forms of the present invention, that the pitman actuating member has imparted thereto the desired movement for converting the rotation of the shaft 6, 6 and 6" to a reciprocating movement in the pitman 8, 8 or 8 in all cases the members 12, 12 and 12 being so mounted that the centers thereof move in a circle, the center of which is the operating shaft.

Vifhat is claimed is:

1. A transmission mechanism including a supporting structure, a shaft j ournaled thereon, a gear carried'by the shaft and revoluble therewith, an arm pivotally connected to the structure and adapted to move in a circle about the longitudinal axis of the shaft, an internal gear revolubly connected to the arm and constantly in mesh with the first named gear, and a driven element pivotally connected to the internal gear.

2. A transmission mechanism including a supporting structure, a shaft journaled therein, a stud spaced from but in alinement with the shaft, a gear upon the shaft, an internal gear extending between the shaft and stud and constantly meshing with the first named gear, means connected to the center of the internal gear and revoluble relative thereto and cooperating with the stud and shaft for holding said internal gear in mesh with the other gear, and a driven element pivotally connected to the internal gear.

3. A transmission mechanism, including a tubular supporting member, two spaced terminals carried therebyat one end thereof, onc of said terminals being provided with a sleeve, a rotary shaft j ournaled in said sleeve and having its end projected between the terminals, a reciprocating shaft mounted in the tubular member and having one end mounted between the terminals, an internal gear, means for connecting the internal gear with the reciprocatory shaft, a gear connected to the projecting end of the rotating shaft and in mesh with the internal gear, a pin carried in axial alinement with the bearing sleeve, and two arms one revolubly connected to the projecting end of the rotating shaft and to the center of the internal gear and the other revolubly connected to the center of the internal gear and the pin, whereby as the shaft is rotated the center of the internal gear will move in a circle, the center of which is the rotating shaft.

In testimony that I claim the foregoing as my own, I have hereto afiixed my signature in the presence of two witnesses.
